Existing evidence on the effects of climate variability and climate change on ungulates in North America: A systematic map Existing evidence on the effects of climate variability and climate change on ungulates in North America: A systematic map
Background Climate is an important driver of ungulate life-histories, population dynamics, and migratory behaviors. Climate conditions can directly impact ungulates via changes in the costs of thermoregulation and locomotion, or indirectly, via changes in habitat and forage availability, predation, and species interactions. Many studies have documented the effects of climate variability...

A systematic review of the effects of climate variability and change on black and brown bear ecology and interactions with humans A systematic review of the effects of climate variability and change on black and brown bear ecology and interactions with humans
Climate change poses a pervasive threat to humans and wildlife by altering resource availability, changing co-occurrences, and directly or indirectly influencing human-wildlife interactions. For many wildlife agencies in North America, managing bears (Ursus spp.) and human-bear interactions is a priority, yet the direct and indirect effects of climate change are exacerbating management...

Ungulate migration in a changing climate—An initial assessment of climate impacts, management priorities, and science needs Ungulate migration in a changing climate—An initial assessment of climate impacts, management priorities, and science needs
Executive Summary Migratory behavior among ungulates in the Western United States occurs in response to changing forage quality and quantity, weather patterns, and predation risk. As snow melts and vegetation green-up begins in late spring and early summer, many migratory ungulates leave their winter range and move to higher elevation summer ranges to access high-quality forage and areas...

Connectivity and climate change toolkit Connectivity and climate change toolkit
The Association of Fish and Wildlife Agencies’ Climate Adaptation Committee charged a small working group in September of 2019 to develop a toolkit focused on climate-informed landscape connectivity. The purpose is to provide state fish and wildlife agency planners and managers with the information necessary to ensure climate considerations are being accounted for and incorporated in the...

A systematic map protocol What are the effects of climate variability and change on ungulate life-histories, population dynamics, and migration in western North America? A systematic map protocol
Climate is an important driver of ungulate life-histories, population dynamics, and migratory behaviors, and can affect the growth, development, fecundity, dispersal, and demographic trends of populations. Changes in temperature and precipitation, and resulting shifts in plant phenology, winter severity, drought and wildfire conditions, invasive species distribution and abundance...

Drought in the U.S. Caribbean:Impacts to Coastal Estuary Ecosystems Drought in the U.S. Caribbean:Impacts to Coastal Estuary Ecosystems
The topography of Puerto Rico and the U.S. Virgin Islands (USVI) is characterized by steep terrain and short distances to the sea. This means that freshwater runs off the islands quickly, coming into contact with seawater in coastal estuaries. The physical characteristics of estuaries change as the tides rise and fall, creating a wide range of habitats that support diverse plants and...

Topographic and Hydrographic GIS Datasets for the Afghanistan Geological Survey and U.S. Geological Survey 2014 Mineral Areas of Interest Topographic and Hydrographic GIS Datasets for the Afghanistan Geological Survey and U.S. Geological Survey 2014 Mineral Areas of Interest
Mineral extraction and associated industries play an important role in the Afghan economy, particularly in the “transitional era” of declining foreign aid and withdrawal of foreign troops post 2014. In addition to providing a substantial source of government revenue, other potential benefits of natural resource development include boosted exports, employment opportunities, and...

Testing a small UAS for mapping artisanal diamond mining sites in Africa Testing a small UAS for mapping artisanal diamond mining sites in Africa
Remote sensing technology is advancing at an unprecedented rate. At the forefront of the new technological developments are unmanned aircraft systems (UAS). The advent of small, lightweight, low-cost, and user-friendly UAS is greatly expanding the potential applications of remote sensing technology and improving the set of tools available to researchers seeking to map and monitor terrain...

A sub-national scale geospatial analysis of diamond deposit lootability: the case of the Central African Republic A sub-national scale geospatial analysis of diamond deposit lootability: the case of the Central African Republic
The Central African Republic (CAR), a country with rich diamond deposits and a tumultuous political history, experienced a government takeover by the Seleka rebel coalition in 2013. It is within this context that we developed and implemented a geospatial approach for assessing the lootability of high value-to-weight resource deposits, using the case of diamonds in CAR as an example...

The role of conflict minerals, artisanal mining, and informal trading networks in African intrastate and regional conflicts The role of conflict minerals, artisanal mining, and informal trading networks in African intrastate and regional conflicts
The relationship between natural resources and armed conflict gained public and political attention in the 1990s, when it became evident that the mining and trading of diamonds were connected with brutal rebellions in several African nations. Easily extracted resources such as alluvial diamonds and gold have been and continue to be exploited by rebel groups to fund their activities...

This toolkit provides a standardized checklist of critical issues relevant to artisanal mining-related field research. An integrated sociophysical geographic approach to collecting data at artisanal mine sites is outlined. The implementation and results of a multistakeholder approach to data collection, carried out in the assessment of Guinea’s artisanally mined diamond deposits, also...

Biodiversity and Climate Change Assessment
Understanding the interplay between biodiversity and climate change is critical for the implementation of effective and lasting solutions to climate change and for maintaining biodiversity and nature’s contributions to people. The USGS was charged by the US Congress in the Fiscal Year 2022 budget with conducting an assessment that characterizes the state of understanding concerning linkages...
The Effects of Climate Variability and Change on Human-Bear Interactions in North America
Negative human-bear interactions are a common problem and management priority for many wildlife agencies in North America. Bears are adaptable to anthropogenic activity and food sources which creates opportunities for conflict with humans, including property damage, livestock depredation, and in severe cases, human injury. Acute climate events and long-term directional climate change can
Understanding the Effects of Climate Variability and Change on Ungulates in North America
Ungulates, or hoofed mammals such as elk, deer, and moose, occupy a diversity of habitats across North America, from Canada’s high arctic to the deserts of Mexico. Ungulates play an important ecological role, helping to regulate processes such as nutrient cycling in forests and grasslands, through their grazing activities. They are also economically and culturally important, providing...
